Description

"CONTAINER AND RECYCLABLE TAMPER EVIDENT CLOSURE ASSEMBLY"
TECHNICAL FIELD
The present invention relates to an assembly of a container and a recyclable tamper evident closure.
BACKGROUND OF THE INVENTION
Tamper-evident closures are known in the art. These closures generally include a cap proper, which is removably associated with the rest of the closure, and a tamper- evident element, providing first-opening evidence.
In most closures, at least one element remains attached to the container after first opening. This element is obviously conceived and designed to remain attached to the container throughout the useful live of the container.
As concerns over the environmental impact of products increase, the need to reduce the environmental impact of safety closures has been increasingly felt.
A reduced environmental impact of an item is known to be obtained by making the item out of parts that are made of the same material or are easily separable.
In the particular case of safety closures, which typically comprise an element that is designed to remain on the container throughout the useful life of the latter, the container is not easily separated from the element attached thereto using standard separation techniques as used in the recycling industry.
Therefore, the element becomes a pollutant in the container recycling process.
WO 2008/95863, US 4156490, US 3001657, GB 407386, GB 374394, GB 362101, FR 1108212 and FR 723220 disclose containers having a neck with lower threads and upper threads, and having a closure applied thereto, with a lower portion engaged with the lower threads and an upper portion engaged with the upper threads. Upon first opening, the lower threads retain the lower portion on the container. Nevertheless, the container does not allow the lower portion to be removed after first opening.
The need is also felt to provide a container that allows easy separation of the closure, for improved recycling of the container, with no element of the closure becoming a pollutant in the container recycling process.
WO 2012/150569 discloses a container assembly with a tamper-evident closure in which the container neck has threads and an engagement surface extending over the threads along at last one longitudinal section of the neck. While this arrangement allows removal of the closure from the neck, it is still involves some complexity in the manufacture of the neck.
GB 2261656, AT 413816, GB 430,600, GB 459,993, WO 98/09879 disclose technical arrangements aimed at preventing accidental opening of the closure and/or at assisting opening of the container when no threads are provided,
Therefore, in light of the above discussed prior art, the object of the present invention is to provide an assembly that allows complete and easy separation of a threaded tamper-evident closure from a container having a threaded neck.
SUMMARY OF THE INVENTION
According to the present invention, this object is fulfilled by an assembly as defined in claim 1.
By providing a neck with a groove and a ramp formed in a projection and engaging with respective portions of the skirt of the tamper-evident closure, the ramp may be used to enlarge the diameter of the portions of the skirt engaged in the groove to thereby easily separate the skirt from the container.

DETAILED DESCRIPTION
Referring to the annexed figures, numeral 100 generally designates an assembly according to an embodiment of the present invention.
The assembly 100 comprises a container 1 and a tamper-evident closure 10.
The container 1 may be made of a plastic material whereas the tamper-evident closure 10 is preferably made of metal, particularly aluminum.
The container 1 has a body (not shown) from which a neck 2 with a mouth 3 extends along a longitudinal axis. The mouth 3 defines the pouring orifice of the container 1 through which the contents of the container 1 may be poured.
The neck 2 extends along a longitudinal axis X-X and terminates on top with an annular rim 4 that delimits the mouth 3. The tamper-evident closure 10 is coupled to the container 1 to open and close the mouth 3, for the contents of the container 1 to be allowed to be or prevented from being poured respectively.
The neck 2 comprises a tubular wall 5 which extends along the longitudinal axis X-X between a lower portion 5a and an upper portion 5b, the annular rim 4 being formed at the upper end of the latter.
The neck 2 further comprises threads 6 formed outside the tubular wall 5, longitudinally beneath and adjacent to the annular rim 4. These threads 6 longitudinally extend between a lower end 6a and an upper end 6b and has crests 6c and troughs 6d. The troughs 6d define the minimum diameter Dl of the threads 6, whereas the crests 6c define the maximum diameter D2 of the threads 6.
The neck 2 further comprises a projection 7 formed outside the tubular wall 5 longitudinally beneath the threads 6, particularly longitudinally beneath the lower end 6a of the threads 6.
The projection 7 has a maximum diameter D3 that is greater than the minimum diameter Dl of the threads 6 and smaller than or equal to the maximum diameter D2 of the threads 6.
The projection 7 has a lower shoulder 7a and an upper shoulder 7b.
The lower shoulder 7a is joined to the lower portion 5a of the tubular wall 5, whereas the upper shoulder 7b is joined to the lower end 6a of the threads 6.
A groove 8 is formed in the projection 7 and extends in a circumferential or helical direction, between a first end 8a and a second end 8b, with a minimum diameter D4 that is smaller than the maximum diameter D3 of the projection 7 and smaller than the maximum diameter D2 of the threads 6.
The groove 8 is joined to the projection 7 by a ramp 9 which extends in the circumferential or helical direction, particularly to join the second end 8b of the groove 8 with a portion 7c of the projection 7, having a maximum diameter D3, to thereby join the minimum diameter D4 of the groove 8 to the maximum diameter D3 of the proj ection 7.
The tamper-evident closure 10 is coupled to the container 1, particularly to the neck 2, to open and close the mouth 3.
Such closure 10 comprises a closure member 11 and a skirt 15, which is connected to the closure member 11 through a frangible portion 16, which is configured to break upon first opening of the container 1 to allow removal of the closure member 11 from the neck 2.
The closure member 1 1 is configured to open and close the mouth 3 and for this purpose it comprises a top wall 12, preferably equipped with a gasket 12a, and a sleeve 13. The sleeve 13 is arranged coaxially outside the neck 2 particularly in the upper part 5b of the neck 2.
The sleeve 13 longitudinally extends between the top wall 12 and a bottom edge 13a and comprises threads 14 removably engaged with the threads 6 of the container 1, to allow removal of the closure member 1 1 from the neck 2 of the container and hence to open and close the mouth 3. Particularly, the threads 14 of the sleeve 13 are formed by rolling the sleeve 13 on the threads 6 of the neck 2.
The skirt 15 is arranged coaxially outside the neck 2 and longitudinally beneath the sleeve 13. Preferably, the closure member 11 and the skirt are formed on one piece and connected via the frangible portion 16. The frangible portion 16 may be formed using breakable axial bridges, a line of weakness or a tear-off tab. Such frangible portion 16 provides evidence that the first opening of the closure 10 and hence the container 1 has occurred.
The skirt 15 longitudinally extends with its maximum diameter D5 between atop edge 15a and a bottom edge 15b.
The top edge 15a of the skirt 15 is connected to the bottom edge 13a of the sleeve 13 via the frangible portion 16.
In one embodiment, the top edge 15b of the bottom edge 15b of the skirt 15 is joined to the lower portion 5a of the tubular wall 5.
The skirt 15 has a a first attachment portion 17 and a second attachment portion
18.
The first attachment portion 17 is engaged inside the groove 8 to hold the skirt 15 longitudinally attached to the neck 2 upon first opening and extends with its minimum diameter D6 between the first end 8a and the second end 8b of the groove 8.
The second attachment portion 18 is engaged with the ramp 9 to join the first attachment portion 17 with the minimum diameter D6 to a portion of the skirt 18 having the maximum diameter D5.
Thus, as the ramp 9 joins the groove 8 with the minimum diameter D4 to the projection 7 with the maximum diameter D3, the second attachment portion 18 joins the first attachment portion 17 with the minimum diameter D6 with the skirt 15 with the maximum diameter D5.
Then, upon removal of the closure member 11 from the neck 2 upon first opening, during disposal of the container 1, the skirt 15 may be easily separated from the neck 2.
For this purpose, the skirt 15 can be rotated relative to the neck 2 in such a direction as to bring the first attachment portion 17 to engage against the ramp 9 and enlarge its diameter to the maximum diameter D5 of the skirt 15.
In this arrangement, the first attachment portion 18 can be disengaged from the groove 8 and the skirt 15 can be slid off the neck 2, i.e. the skirt 15 can longitudinally move outside the threads 6 of the neck 2.
In order to assist the rotation of the skirt 15 and the enlargement of the diameter of the first attachment portion 17 as a result of the engagement with the ramp 9, the ramp 9 forms a slope angle ranging from 15° to 45° with the groove 8.
In one embodiment, the groove 8 extends in the projection 7 longitudinally beneath the frangible portion 16. Particularly, in a circumferential arrangement, the groove 8 is located beneath the frangible portion 16, whereas in a helical arrangement, where the first end 8a acts as the top end and the second end 8b acts as the bottom end, the top end 8a is located beneath the frangible portion 16. This will allow the frangible portion 16 to break upon first opening without altering the engagement of the skirt 15 with the projection 7, particularly with the groove 8 and the ramp 9.
The above disclosure clearly shows that the present invention fulfills the intended objects.
Those skilled in the art will obviously appreciate that a number of changes and variants may be made to the arrangements as described hereinbefore to meet incidental and specific needs. All of these variants and changes fall within scope of the invention, as defined in the following claims.
